WINDOVW-SASH.

SPECIFICATION forming part of Letters Patent No. 256,644, dated April18, 1882.

Application filed February 18, 1882. (No model.)

To all whom it may concern Be it known that 1, JOHN F. 00X, of Brooklyn,in the county of Kings and State of New York, have invented a new anduseful Im provcment in Window-Sashes, of which the following is aspecification.

The object of this invention is to facilitate the work of cleaning andglazing windowsashes and the ventilation of rooms.

The invention relates to that class of windowsashes that may be turnedon side pivots; and it consists in centrally pivoting to the edges ofthe hanging stiles, by means of a novel device, sliding pieces that movein the pulleystiles, and to which the sash counterbalanceweights may beconnected; and, further, of a sash pivoting or swiveling device of novelconstruction, and a novel diagonally-moving sash fastening and a lockingdevice, all of which will be'hereinafter set forth.

Figure l is a front elevation of a windowframe with my improved sash inposition. Fig. 2 is a sectional elevation of a portion of the same onlinear m, Fig. 1. Fig. 3is a crosssection of a portion of the same online 9 y,

Fig. 1. Fig. 4 is an elevation of a portion of a sash, showing thesash-fastening device in position. Fig. 5 is a sectional elevation of myimproved sash swiveling or pivoting device. Fig. 6 is a plan of thesame.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a windowsash frame, of which A are thelining parting strip beads, and B B represent the upper and lowersashes, respectively.

It will be seenthat the hanging stiles O of the sashes B B arev reducedor cutaway to enable them to swing clear of the parting-strip beads A.In order to secure the said sashes B B in place, sliding strips orpieces E E, adapted to fit in the pulley-stiles F, are provided of equaldepths and widths with the hanging stiles C, and to these strips E thesashes B B are centrally pivoted on either side by the pivoting orswiveling devices G.

A swiveling or pivoting device, G, consists of a centrally-perforatedplate, G, having on its under side a collar, 0, of smooth interior,

of asecond centrally-perforated plate, G having on its under side acollar, b, of screwthreaded interior, and of a screw-bolt, G, de-

'the collar or being inserted in a corresponding socket, 01, formed insaid strips E, and the plates G are in like manner secured upon theouter faces or edges of the sash-hanging stiles 0. Then the screw-boltsG are inserted in place,

'as indicated in Figs. 3, 5, and 6, and screwed in as tightly as may beconsistent with the free swiveling of the said sashes B B. The sashes BB, with their connected side strips, E E, are then set in place, and, ifdesired, the usual cord and counterbalance-weight may be attached in thecustomary manner to the said strips, as indicated at K, Fig. 2, forholding the sashes at any desired elevation.

In the edge of each sash-hanging stile, and throughout nearly the wholelength thereof, is] formed a mortise or socket, f, while in eachopposite strip, E, is formed a corresponding socket or mortise, g.Fastening-tongues H, having diagonal slots t, are held in the mortisesfby means'of pins k, that passthrough .the sash-stiles and the slots 6,so that said tongues H may be moved diagonally upward entirely withinthemortises f, that the said sashes B B may be turned freely on theirpivots G or said tongues H, when the sashes are restored to a verticalposition, may fall of their own gravity diagonally downward, asindicated in Figs. 3 and 4, into the opposite mortises, 9, therebyholding said sashes and the strips E E locked and parallel with eachother and closing the joints between them to keep out the weather.

A knob or lifter, m, secured in each tongue H, and projecting outthrough a diagonal slot, at, in the face of each hanging stile, servesas a handle by which to move the tongue H when it is desired ,to fix thesashes in vertical position, or to unfasten and turn them in any otherposition.

When the sashes B B are closed they may be firmly held together, so thatthey cannot be opened from the outside nor be rattled by the wind, bymeans of a thumb-screw, I, that is passed from the inside through thehorizontal meeting stiles, as indicated in Fig. 1,

Window-sashes constructed and arranged in this manner can readily beturned at any desired angle and be reversed for the purposes ofventilation, cleaning, or glazing, whereby greater comfort to theoccupants of the room and the safety of those working upon the windowsare assured.

I am aware that it is not new to swivel or pivot window-sashes; hence Ido not broadly claim a pivoted or swivelcd window-sash; but

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A window sash constructed substantially as hereinshown and described, consisting of mortised sash B, mortiscd slidingstrips tion therewith of the pivoting device G, consisting of plate G,provided with collar a, of smooth interior plate, G provided with collar1), of screw-threaded interior and screw-bolt 0 G arranged and operatingsubstantially as herein shown and described.
